I’m starting to see the possibilities in this, actually… probably something to do with bits of roughly crushed cocoa in the tea bag, maybe some of that butter flavoring like they sometimes use in icing… vanilla bean? Could you fit vanilla bean in there? Question is, how does one make it that sweet inherently while in the bag–or do you just add your own sugar, like normal tea?

I would think that it be mostly in the aroma and the taste would be rather subdued, not actually sweet. I don’t know a whole lot about flavored teas, but my experiences with them are that the taste is more “implied” than in your face.
